Storage I/O
Writes and re-reads a 4 MB test file to measure actual disk throughput — not a marketing spec.
Real Performance Check
Know what's actually slowing your phone down.
PhoneCare runs honest, on-device benchmarks — storage I/O, frame jank, thermal headroom, runtime pressure — and gives you a score you can trust. No fake "boost" buttons, no RAM-cleaner theatre.
- 100% on-device measurement
- No data leaves your phone
- Score changes only after re-measure
Four measurements. One honest score.
Every component score comes from a real benchmark. Nothing is estimated, nothing is fabricated.
Frame Jank
Samples 180 frames (about 3 seconds) before any animation starts, counting dropped frames during the test.
Thermal Headroom
Reads the system thermal API (Android 10+). If charging, we flag it so you don't misread the reading.
Runtime Pressure
Measures available memory and process load under realistic conditions — not synthetic "free RAM" numbers.
How PhoneCare works
Three steps. Under a minute. No permissions you don't need.
-
1
Scan
Tap Start check. PhoneCare runs the four benchmarks in sequence while the progress ring follows the real work — not a fake animation.
-
2
Score
You get a weighted score from 0–100, colour-coded across five bands: Excellent, Good, Fair, Needs Attention, and Poor.

Fix
If issues are found, PhoneCare shows specific, measurable actions — free up storage, reduce thermal load — and re-measures so you can see the real delta.
The anti-fake rules
PhoneCare is built on a set of non-negotiable commitments.
No "boost" theatre
We never claim your phone is faster unless we re-measured and the score actually improved by more than 5 points.
No misleading jank copy
Every frame-drop reading is labelled "during test" because that's what we measured — not a permanent verdict on your device.
No cross-class comparisons
A budget device is compared against the budget baseline. We don't shame your phone against a flagship to sell you a fix.
No fake scan animation
The progress ring only advances after real work completes. If the benchmark is slow, the ring is slow.
Check your phone honestly.
PhoneCare is free on Google Play. Android 8.0 and above.
Download on Google PlayFrequently asked
- Does PhoneCare upload my data?
- No image, file, or personal content ever leaves your device. Benchmarks run locally. See the privacy policy for the full breakdown.
- Why does the app ask for photo access?
- Only if you open the Duplicate Images cleanup feature. We read image metadata and a 64 KB hash locally to find duplicates — nothing is uploaded.
- Will it make my phone faster?
- PhoneCare measures and reports. Where a real improvement is possible (freeing storage, reducing heat), we tell you — and re-measure to prove the delta.
- Which Android versions are supported?
- Android 8.0 (API 26) through Android 15. Thermal-headroom metrics require Android 10+; on older versions we mark that component as unavailable rather than guessing.
